Title: [Debian R3 and R4] Installing Mali Binary Drivers
Post by: tlhingan on September 23, 2013, 09:41:48 pm
These instructions (http://linux-sunxi.org/Binary_drivers) are a bit wonky to follow for a n00b, so here's what is hopefully a simpler and more complete rewrite of those instructions.

edit /etc/modules to add
ump
mali
mali_drm


create a file in /etc/udev/rules.d/ called "50-mali.rules" containing
KERNEL=="mali", MODE="0660", GROUP="video"
KERNEL=="ump", MODE="0660", GROUP="video"


reboot
after loging in, type "lsmod" and make sure "mali" and "ump" are listed
then
apt-get install build-essential xorg-dev xutils-dev libdrm-dev x11proto-dri2-dev libltdl-dev libtool automake
git clone https://github.com/linux-sunxi/sunxi-mali.git
cd sunxi-mali
git clone https://github.com/robclark/libdri2
cd libdri2
./autogen.sh --prefix=/usr
make
make install
cd ..
git submodule init
git submodule update
make install
cd ..
git clone https://github.com/ssvb/xf86-video-sunxifb.git
cd xf86-video-sunxifb
autoreconf -vi
./configure --prefix=/usr
make
make install
cp xorg.conf /usr/share/X11/xorg.conf.d/99-sunxifb.conf

I guess one could copy/paste the last block into a script file.
I'll try that next time I need to setup another image.

After doing all this, startx say : no screens found!

Any help please.

You sould probably replace

cd xf86-video-sunxifb.git

with cd xf86-video-sunxifb

Yes this is a mistake in the script, but is not the problem

Yes!
Thanks for catching that!

Yes, there's a mistake in the provided configuration file.
Change the driver specified in 99-sunxifb.conf from "fbturbo" to "fbdev".

With modification in conf file startx is now OK.
I was thinking that installing mali driver will improve mplayer performance with HD video but in fact no.
Is this normal?

Mali is the GPU driver.
AllWinner's multimedia (video & image) acceleration co-processor is called CedarX and its open source support in Linux is in alpha state at the moment (although I think it is well supported in Android via some binary blob).
http://linux-sunxi.org/CedarX (http://linux-sunxi.org/CedarX)
You can try changing mplayer renderer to gl or gl2 (OpenGL).

Edited top post to include /usr prefix for the libdri2 autogen
Also added mali_drm as a module to load.
And this does work quite nicely as a script.

Does this mean that these drivers are not installed on the image one can download on this site, or is this for those who create their own?

They are not on the downloadable image - not everyone needs them.
You can use this procedure to download and install them on the image you downloaded.

*need* ? :)
It will give faster graphics i guess?, if I manage to get everything up,I want to use the a20 for mediastreaming, but heaps of debian stuff to learn first.

Edited top post to remove the editing step of xorg.conf.
fbturbo now loads with this config.

To make a scrip file out of the code:

Thank you so much for these instructions. They executed without error, but I don't see a difference in performance. I am testing with glxgears "apt-get install mesa-utils" (I know not the best benchmark, but it is easy to get). I ran glxgears with and without the mali module from a terminal in lightdm and from ssh with "Xorg" then "glxgears -display :0". The frames per second were around 40.

I am testing with the debian-release5 image from olimex. Also, my display is the 10" lcd from olimex if that matters.

Are you guys seeing a speed up with the binary drivers? I certainly may have messed something up during my install. Thank you

I just wrote up a how-to to get the CedarX (VPU) working. I now have h264-1080p video running without frame dropping and perfect audio sync in mplayer. :)

I'm trying to get decent speed on emulated arcade games, so it's not entirely related to gpu driver, but acceleration should give some boost. Using metal slug on advancemame ad benchmark, I didn't notice any improvement. using open box instead of xfce and starting only advancemenu+advancemame was the only thing that increased (still poor) performances.

I tried to start glxgears, too, and have the same results, maximum 40fps or so. I wonder if it's the maximum capability of this GPU or if the driver is poorly implemented...
